MINNEAPOLIS (AP) - A Minneapolis astronomy professor says he's stunned by the attention he's getting for suggesting the signs of the zodiac are all wrong.

Parke Kunkle said in a newspaper interview that the Earth's wobbly orbit means it's no longer aligned to the stars in the same way as when the signs of the zodiac were first conceived. He said that means when astrologers say the sun is in Pisces, it's really in Aquarius, and so on.

The story went viral, with thousands of people fretting on social networks that their sign might change.

But Kunkle, who teaches at Minneapolis Community and Technical College, said Friday that the shift is "2,000-year-old information."

Shelley Ackerman, spokeswoman for American Federation of Astrologers, said she's been swamped with e-mails from worried clients, but tells them "this doesn't change your chart at all."
